The effects of aging and IQ on performance were examined in three two-choice tasks: numerosity discrimination, recognition memory, and lexical decision. The experimental data, accuracy, correct and error response times, and response time distributions, were well explained by Ratcliff’s (1978)diffusion model.
IQ is not a measure of innate intelligence. If used to measure innate intelligence, IQ scores will be biased. **FACT: Studies show that g is better at predicting a person’s occupational success in comparison to another person than aptitude tests or prior work experience. In other words, people with a higher g tend to do better in the workplace.

May 04, 2006 · In the first experiment, the college students performed 34% faster than the adults, making it clear that motor speed can be a major contributor …
For accuracy in associative recognition, the interaction of age and IQ was striking. For the highest IQ participants, the drop in performance with age was precipitous-- from about 75% correct to about 65% to close to 50% (floor), for college age, 60-74 year old, and 75-90 year old participants, respectively.
As we age and accumulate new knowledge and understanding, crystallized intelligence becomes stronger. As you might expect, this type of intelligence tends to increase with age. 6 The more learning and experience you have, the more you build up your crystallized intelligence.Aug 23, 2021
The Flynn effect refers to a secular increase in population intelligence quotient (IQ) observed throughout the 20th century (1–4). The changes were rapid, with measured intelligence typically increasing around three IQ points per decade.Jun 11, 2018
Practical intelligence appears to peak in midlife and then decline, following closely the changes observed in the underlying cognitive abilities associated with specific everyday problems.
The majority of researchers believe that IQ remains stable with age but that the components of a person's intelligence change. The changing components of intelligence can usually be described as fluid intelligence and crystallized intelligence. Fluid intelligence is the ability to reason and process information.Sep 26, 2021
How does aging affect crystallized and fluid intelligence? cross-sectional studies and longitudinal studies have shown that fluid intelligence declines in older adults, in part because neural processing slows. Crystallized intelligence tends to increase. The stability of intelligence test scores increase with age.
Richard Nisbett, professor of psychology at the University of Michigan: Yes, your IQ can change over time. But [IQ] tests give you the same answer to a very substantial extent, even over a period of year. The older you are, the more stable your test score will be.May 30, 2013
As in the movie “Idiocracy,” it was suggested that average intelligence is being pulled down because lower-IQ families are having more children ("dysgenic fertility" is the technical term). Alternatively, widening immigration might be bringing less-intelligent newcomers to societies with otherwise higher IQs.May 22, 2019
After any brain injury, even a mild one, there tends to be a drop or loss of IQ, but this score usually improves as time passes. This fact leads researchers to argue that most “intelligence loss” after brain injury is really just a result of trauma.Dec 3, 2019
Fluid intelligenceCrystallized intelligence is the ability to use knowledge that was previously acquired through education and experience. Fluid intelligence declines with age, while crystallized intelligence is maintained or improved.Jan 8, 2019
Scientists have long known that our ability to think quickly and recall information, also known as fluid intelligence, peaks around age 20 and then begins a slow decline.Mar 6, 2015
Age is often associated with a decline in cognitive abilities that are important for maintaining functional independence, such as learning new skills. Many forms of motor learning appear to be relatively well preserved with age, while learning tasks that involve associative binding tend to be negatively affected.Aug 28, 2015
Erikson’s (1950) model of adult psychosocial development outlines the significance of successful involvement within one’s relationships, work, and community for healthy aging. He theorized that the consequences of not meeting developmental challenges included stagnation and emotional despair.
Erikson’s (1950, 1968) model of psychosocial development is routinely utilized as a foundational framework for understanding adult human development across the lifespan ( Busch & Hofer, 2012; Schoklitsch & Baumann, 2012; Slater, 2003; Sneed, Whitbourne, Schwartz, & Huang, 2012 ; Vaillant, 1993, 2012; Westermeyer, 2004; Whitbourne, Sneed, & Sayer, 2009; Wilt, Cox, & McAdams, 2010 ).
Participants were a subsample of 159 men drawn from the Study of Adult Development, an over 75 year longitudinal study that has followed two cohorts of men from late adolescence until late life.
We first examined the means and standard deviations of demographic variables and neuropsychological variables in the full sample and separately in the College sample and Inner City sample. As can be seen in Table 2, t-tests revealed that on average the college sample were older, had higher adolescent IQs and levels of education.
Erikson’s model of psychosocial development has been central to modern understanding of the ways in which individuals adaptively engage with relationships, vocations, and community across the lifespan ( Busch & Hofer, 2012; Kroger, 2014; Sneed et al., 2012 ; Vaillant, 1993, 2012; Wilt et al., 2010 ).
1 Analyses comparing the participating subsample of College and Inner City men with those in their respective cohorts showed no significant differences on measures of adolescent intelligence, midlife social and marital adjustments, or occupational success at midlife (all t’s<2.0, p ’s>.05).
